I have ceiling fans. Can I use a Vornado Air Circulator too?

Certainly, but you may need to experiment as the strong downdraft of the ceiling fan may create enough of a disturbance in the room as to minimize or negate the benefits of the Vornado Air Circulator. Interestingly, we have had a number of consumers tell us they quit using their ceiling fans because the circulation and comfort delivered by Vornado is gentler and more complete.
